✦ Synopsis

The effects of aging of source materials during the synthesis of ZSM-5 films on quartz surfaces were investigated. To verify these aging effects, three sets of samples, having a specified composition but different aging periods, were prepared. When aged gels or solutions were used, the resulting ZSM-5 crystals did not form a film but a powder, and the powdery crystals were easily removed from the quartz surface by washing. However, when unaged mixtures were used, ZSM-5 films or silicalite crystals did form on the quartz surface, and the ZSM-5 crystals were found to be firmly bonded to the quartz surface.

ZSM-5 synthesis gels were aged during 18-72 h at temperatures between 30 and 90 8C. After addition of the cationic surfactant cetyltrimethylammonium bromide these so called ''seeding gels'' were crystallised at 120 or 150 8C. From gels aged at 60 8C, ZSM-5 crystals possessing uniform mesopores with

High-silica ZSM-5 crystals were grown in the microgravity environment (10 Γ€3 Β±10 Γ€6 g) of the space shuttle from precursor solutions held unmixed until activation on orbit. The Β―ight crystals grown from untreated (not heat-treated) silica gel grade 12 had the intergrown disk morphology and were larg
